摘　　要：对宜昌磷矿进行了工艺矿物学研究,测定出了矿石的化学成分、各组分的赋存状态、矿物的嵌布特征和单体解离度.研究表明宜昌磷矿中含P2O5、CaO、SiO2、Al2O3、MgO、Fe2O3、K2O、F、S、Na2O等化学成分,胶磷矿、碳酸盐矿物、石英质矿物和粘土质矿物是其主要矿物单体,它们总质量分数达到98.2%.有96%的胶磷矿嵌布粒度和93%的碳酸盐矿物嵌布粒度大于0.0784 mm,而且它们的单体解离度在三个粒级均大于90%,属中粒嵌布.The process mineralogy of phosphate ores in Yichang including chemical compositions,occurrence state,grain size,embedded feature of minerals and monomer dissociation degree was studied.The results show that Yichang phosphate ores contains many complex chemical compositions which contain P2O5,CaO,SiO2,Al2O3,MgO,Fe2O3,K2O,F,S,Na2O,and et al.Collophane,carbonate,quartz mineral,and clay mineral are the main mineral components of phosphate ores,whose content is up to 98.2 %（w/%）.The particle assemblage size of 96 % collophane and 93 % carbonate is above 0.0784 mm which should be middle particle assemblage size distribution.The monomer dissociation degree of collophane in the-0.037 mm,0.037～0.05 mm,and 0.05～0.074 mm fractions,are all above 90 %.
